BROILER.

SPECIFECATION forming part of Letters Patent No. 320,668, dated June 23,1885.

Application filed September 12, 1884.

(No model.) Patented in England April 22, 1884, No. 6.656, and in FranceDecember 18, 1894,

To all whom it may concern.-

Be it known that I, ANTOINE MARIE LOUIS MA'rHIoLY, a resident ofLIsleen-Jourdain, in the French Republic, and a citizen of said FrenchRepublic, have invented certain new and useful Improvements in Broilers;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being badto the accompanying drawings, and to letters or figures of referencemarked thereon, which form a part of this specification.

This invention has for its object certain improvements in gridirons,whereby the efticiency of use, as well as the durability of suchutensils, is materially enhanced; and itconsists, in combination with agridiron, with or without fixed legs, of foldable and vertically-adjustable legs, whereby the proximity of the utensil to the combustiblemay be adjusted within certain limits.

The invention further consists in the combination, with the gridiron, ofa fire-guard to protect the food placed thereon against the action ofthe fire when the utensil is employed for cooking food in an openfire-place.

The invention further consists in certain details of construction, allsubstantially as hereinafter more fully described, and as illustrated inthe accompanying drawings, andin which Figure l is a side elevation ofthe gridiron, the adjustable legs being folded up. Fig. 2 is a like viewwith the adjustable legs turned down. Fig. 3 is a perspective view ofthe gridiron; and Figs. 4 and 5 are detail views.

The gridiron proper, A, may be constructed in any usual or preferredmanner, and be composed of any number of wires, a, arranged transverselyor longitudinally, or in any other desired manner, and at any desireddistance from one another, according to the uses made of the gridiron.

For use in open fire-places I provide the utensil with four stationarylegs, a, secured to the corners thereof, though these may be dispensedwith when the gridiron is designed for use both on a stove and in anopen fire-place. In either of these cases it is desirable to providemeans whereby the distance of the article treated relatively to thesource of heat may be regulated, and to this end I employ foldable legsadapted for vertical adjustment, constructed and arranged as' follows:The two pairs of adj ustable legs L and L are each formed of a singlewire bent at right angles, to form ateach end the legs proper, andhaving the central cranked portion, Z. The wires L L are pivoted inloops 1, secured to or formed by two of thewires a of the gridiron atsuitable points, and to the cranked portion Z of each wire L L isconnected one end of a connecting rod or wire, V W, the former rod, WV,being connected to crank Z of wire L, and the rod WV to the like crankof wire L. The opposite ends of the connecting-rods WV WV are connectedto opposite ends of a cross-head, 0,

formed by a wire secured to a boss or footpiece, B, to which is alsosecured the operating wire or rod R.

, H is the handle of the gridiron, formed by one or two wires, h,arranged to form at their outer end a suspension-loop, h. These wiresare secured within a sheet-rnetal inclosing' sleeve, S, that hasopenings 5 above and below the handle-wires, through which theoperating-rod R passes, said rod projecting some distance above thesleeve S, at which point it is bent to form a loop or hand-hole, r, theextension 1' of said bent portion having its outer or free end, r, bentat right angles to form a hook, 1-, adapted to engage one of the holes1, 2. 3, 01-4, formed in the sleeve S.

' \Vhen the parts are in the position shown in Fig. 3, the hook r of thelocking-arm? of the handle being in engagement with the hole 1, the legsL L will be fully extended and the gridiron will rest thereon solely,the legs a being elevated from the supporting -surface of the gridiron.If it is desired to bring the the gridironcloser to the source of heat,it will only be necessary to raise the same slightly by seizing it withthe left hand by the handle and when slightly raised turning theoperating-rod R in the direction of the arrow 00, Fig. 3, until the hookr of lockingarm r engages the hole 2. This partial rotation of the rod Rimparts a like rotation to the cross-head O, and through theconnecting-rods W \V the two pairs of legs L L will be moved in oppositedirections,or from each other. By bringing the hook of the locking-arm rinto engagement with the hole 3 the two pairs of legs L L will be movedstill farther from each other and the gridiron correspondingly lowered,and by moving the arm 1" so that its hook will engage the hole 4 the twopairs of legs L L" will be fully folded up, as shown in Fig. 1. When theparts are in the position last-above described,and shown in said Fig. 1,the gridiron will rest on the fixed legs a and on the foot-piece or bossB, as shown. By means of this construction I provide a support for thegridiron at five pointsnamely, at the four corners and at the handl-ihus avoiding any liability of upsetting.

When broiling or toasting in an open fireplace, the food upon thegridiron is liablento be scorched and burned or become smoked by thewood or coal fire back of it. To avoid this I apply to the rear end ofthe gridiron a guard-plate, G, extending vertically therefrom, wherebysuch food is effectually pro tected from the action of the fire back ofthe gridiron. This guard-plate may be soldered to the front cross-wire,c of the gridiron, or it may be detachably connected therewith byforming at each corner a loop or eye, a and securing to the ends of thesheet-metal guard G leg-wires 9, adapted to be stuck into said loops,asshown in Fig. 5. In this mannerthe guard G may be readily removed whenits use is not required, and when worn out from any cause it may bereadily removed and a new one substituted at a trifling expense.

Instead of the sheet-metal sleeve S, the-handle may be formed entirelyof wires bent into the shape of loops or eyes 1, 2, 8, 4, and 5, theloop or eye 5 serving as a bearing for the rod R, as shown in Fig. 4. Iprefer, however, to employ the metallic sleeve S, for the reason that itfurnishes a re-enforce to the handle and a more substantial bearing forthe said rod R underneath and above the handle-wires If desired,brace-wires D D may be secured to the under side of the sleeve S, andtheir outer ends bent into the form of aloop or eye, (I (I, throughwhich the rod B may be passed to provide a still more secure bearing forsaid rod, as shown.

Having now particularly described my said invent-ion, what I claim asnew, and desire to secure by Letters Patent, is

1. The combination, with a gridiron, of adjustable legs whereby saidgridiron may be adjusted vertically relatively to the source of heat,for the purpose specified.

2. The combination, with a gridiron, of a detachable guard-plate, G,appliedito one end of the gridiron, substantially as and for the purposespecified.

3. The combination, with a gridiron provided with fixed supporting-legs,of adjustable auxiliary legs of greater length than the fixed legs, forthe purpose set forth.

4. The combination, substantially as herein described, with a gridiron,of adjustable legs, an operating-rod connected with said legs, and astop for locking the legs in position when adjusted, for the purposespecified.

5. The combination, substantially as herein described, with a gridiron,of adjustable legs, a cross-head, connecting-rods for connecting saidlegs with the cross-head, and a stop for locking the cross-head intoposition, for the purpose set forth.

6. The combination, substantially as herein described, with a gridironand its handle, of four adjustable legs arranged in pairs, a crosshead,connectingrods for connecting the legs in pairs to opposite ends of thecross-head, an operating-rod for rotating said cross-head, and stopsformed on or secured to the handle for locking the cross-head inposition when adj usted, for the purposes specified.

7. The combination, substantially as herein described, with the gridironA, its handle H. and the sleeve S, provided with holes 1 2 3 4 5, of thelegs L L, the rods WV WV, the crosshead 0, the rod R. and locking'arm1", for the purpose specified.

In testimony that I claim the foregoing I have hereunto set my hand this20th day of August, 1884.
